i VEHICLE SIGNAL APPARATUS.

Speciqaton of Letters Patent.

Patented Nov. 30, 1915.

Application inea neeember 14, 1914. serial No. 877,073.

To a'ZZ whom t may concern:

Be it known that I, BoRNE'rr L. BoBRoFF,

av citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Vehicle Signal Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof.

Myinvention consists in what is herein particularlyset forth with reference to the 'accompanying drawings and pointed out in vthe claims of this specification, its object being to provide motor vehicleswith simple, economical and eiiicient means by which' paratus as aforesaid, and Fig. 3, a cross-.sec-

tion of the same indicated by ,line 3--3 in Fig. 2. y

Referring by numerals to the drawings, 4

are separately attachable to a windshield standard 5 or other convenient stationary prt of a motor vehicle, at a side of the same.

Fig. 3 one of the housings is shown in connection with a clamp 6 attached to a support such as one of thewindshield standards 5 aforesaid, and each housing is made separable to Extending from each housing is a bracket 7 to which the coils 8 of an electro-magnet are attached, the magnet being in circuit with a conveniently arrangedjbattery 9 or other source of electricity with the vehicle, and the make and break of the circuit iscontrolled by a push-button 10 or other suitable switch. In pivotal connection with lugs 11,

of the housing is a lever 12 to which the armature13of the electro-magnet vis attached',v

and the lever has, play in a slot of said housing. A spring 14, in the housing, is coneffect the signaling operation hereinafter described.

The inner end of the lever is a sector-rack 16 .in mesh with the pinion-hub 19 of a larger gear-wheel 20 having an axle 21 supported in the housing, and the largest gear- Wheel meshes with a pinion 22 that is also mounted in said housing and meshed with a rack 23 of a horizontal hollovsT arm 24 for Y which the aforesaid housing is provided with a guide 25 as a part of the same, one end of the guide being enlarged to constitute a hood 25 in which a visible signal a.t-

- tact-screws first aforesaid, and they constiy tute terminals of an electric-circuit contached to said arm is normally concealed.

The arm 24 is a visible signal in itself,

and it is preferable to have its outer end fast in a target 26 simulating a human hand,

as is herein shown. The target is apertured.

and in the aperture is an incandescent electric-lamp 27 for which the arm 24 is pro vided with a socket. The lamp wires 28 and 29 extend through the arm 24, and they are vrespectively attached to contactscrews 30,

31, in an insulating-bracket 32 extending at a right angle to said arm to which it is fastened. Other contactl screws 33, 34, engaging a block 35 of insulation attached to the housing 4, are inthe path of the controlled, as to make-and-break, by a switch 37. As herein shown', the same source of electricity may be included in both of the circuits shown and described. i

provide for access to the interior path. On release of the lever there is connected to the lever and a screw-post 15, and

.said lever is operated either electrically or manually againstl resistance of the spring to By manual operation of the lever I12 or herein described gear-train is put in motion to run out the arm 24 and target 2,6 therey by closing the electro-magnet circuit, the

with, and the switch-points of the lamp-cir- 'i cuit being bridged, the lamp 27 will be energized when'thev contacts 31 and 32 close on the other` contacts 33, 34, in their` outward traction of the spring 14 to return said lever and parts in gear-train therewith to th normal position shown in Fig. 2.v

Either signal is run out from normal position to indicate a direction' of turning proposed by the driver of the. vehicle equipped therewith,land said signal vmay be kept displayed until the turning is completed. The

signal-mechanism can be arranged to be operated by a foot of the driver, in which case said driver has the use of both hands to control the vehicle when making a turn.

I claim:

l. The combination of a housing attachable to a motor vehicle at a side of the same and having a horizontal guide-extension, a lever fulcruined in connection with the housing, a signal in gear-train connection.

lamp is included when the signal is displayed. i.

2. rI he combination'of a housing attachable to a motor vehicle at a side of the same and having a horizontal guide-extension, a lever fulcruined in connection with the housing, a signal in gear-train connection with the lever to be moved horizontally out and in the guide-extension of said housing, an electric-lamp constituting part of the signal, its Wires being attached to insulated contacts carried by said signal; and electric-circuit terminal contacts having insulated connection with the aforesaid housing in the outward path of the first named contacts.

3. The combination of a housing attachable to a motor vehicle at a side of the same and having, a horizontal guide-extension, a lever fulcru'med in connection with the housing, and a signal having a hollow rack-arm in gear-train connection with the lever, said signal being normally concealed by said with the signal having its Wires extended through said arm and attached to insulated outer contacts therewith, and electric-circuit contacts having insulated connection with the aforesaid housing in the outward path of the contacts irst named.

4. rIhe combination of a housing attachable toa motor vehicle at a side of the same and having a horizontal guide-extension, a bracket with the housing and to which an electro-magnet is i attached, a spring-controlled lever fulcrumed in connection with said housing and constituting the armature of the magnet, a signal in gear-train connection with the lever to be moved horizontally out and in the housing in which it is normally concealed, means for energizing said magnet to operate said lever against spring-resistance, an electric-lamp constituting part of the signal,. an electric-circuit in which the lamp is included when the signal is displayed. y f

In testimony that I claim the' foregoing I have hereunto set my hand at Milwaukee in the county of Milwaukee and State of Wis consin inthe presence of two witnesses.
